Lagrangian submanifolds in complex space forms satisfying an improved equality involving δ(2,2)
(Institutum Mathematicum Universitatis Debreceniesis, 2013)
It was proved in [8, 9] that every Lagrangian submanifold M of a complex space form M˜ 5 (4c) of constant holomorphic sectional curvature 4c satisfies the following optimal inequality: δ(2, 2) ≤ 25 4 H 2 + 8c, (A) where ...

Two-neutron transfer in the 6 He + 120 Sn reaction
(American Physical Society, 2018)
A large yield of α particles produced in the 120 Sn ( 6 He , α ) reaction was measured at 20.3-, 22.2-, 22.4-, and 24.5-MeV bombarding energies. The α particles are distributed over a broad energy range ...

Using physical unclonable functions for internet-of-thing security cameras
(Springer, 2018)
This paper proposes a low-cost solution to develop IoT security cameras. Integrity and confidentiality of the image data are achieved by cryptographic modules that implement symmetric key-based techniques which are usually ...

Preferential oxidation of CO on a La-Co-Ru perovskite-type oxide catalyst
(Elsevier, 2017)
A Ru-containing perovskite-type oxide La(Co,Ru)O3 of nominal composition LaCo0.8Ru0.2O3 was prepared by ultrasonic spray combustion and tested for the preferential oxidation of CO (PROX). EXAFS indicated that Ru adopted ...

Functional diversity of ectomycorrhizal fungal communities is reduced by trace element contamination
(Elsevier, 2018)
Trait-based approaches are useful tools to explain ecological assembly rules and ecosystem functioning. However, their use for soil microbiota has not been explored in depth yet. We explored trait-based functional changes ...

Oxidoperoxidomolybdenum(VI) complexes with acylpyrazolonate ligands: synthesis, structure and catalytic properties
(The Royal Society of Chemistry, 2018)
Oxidoperoxido–molybdenum(VI) complexes containing acylpyrazolonate ligands were obtained by reaction of [Mo(O)(O)2(H2O)n] with the corresponding acylpyrazolone compounds HQR. Complexes Ph4P[Mo(O)(O2)2(QR)] (R = neopentyl, ...

Refined empirical stability criterion for nonlinear Schrödinger solitons under spatiotemporal forcing
(2011-08-25)
We investigate the dynamics of traveling oscillating solitons of the cubic nonlinear Schrödinger (NLS) equation under an external spatiotemporal forcing of the form f(x,t)=aexp[iK(t)x]. For the case of time-independent ...

Using a process-based stomatal model in olive and its potential application to deficit irrigation studies
(INSTITUTO DE RECURSOS NATURALES Y AGROBIOLOGÍA (CSIC). SEVILLA (ESPAÑA)., 2012-09)
Over the last years modeling plant transpiration has been pointed out as a powerful tool to optimize the management of irrigation in fruit trees. In this study we tested the hydromechanical model of stomata functioning ...

Molybdenum-catalyzed enantioselective sulfoxidation controlled by a nonclassical hydrogen bond between coordinated chiral imidazolium-based dicarboxylate and peroxido ligands
(MDPI, 2018)
Chiral alkyl aryl sulfoxides were obtained by molybdenum-catalyzed oxidation of alkyl aryl sulfides with hydrogen peroxide as oxidant in mild conditions with high yields and moderate enantioselectivities. The asymmetry is ...
